Starting Android app development requires a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release targeted and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI uniformity, speed, and compatibility across different OS versions and display sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
